Automatic Power Factor Correction (APFC) panel is an electrical control panel used to maintain the power factor of a power distribution system. It is used in industrial and commercial applications to improve energy efficiency, reduce energy costs, and increase the lifespan of electrical equipment.

The APFC panel also has several protective features such as overvoltage protection, under-voltage protection, overcurrent protection, and short circuit protection. These features ensure the safe and reliable operation of the APFC panel and the connected electrical equipment.
